From BS OHSAS 18001 to ISO 45001

Apr 03, 2025

Our 8-step plan for conversion to ISO 45001

When transitioning from BS OHSAS 18001 to ISO 45001, it is advisable to create an internal action plan outlining all necessary steps, from training on the new standard to final certification. We recommend eight steps for developing such an action plan. Read all about it in this blog.

What does the transition mean for your organization?

ISO 45001 replaced BS OHSAS 18001 in March 2018. The revision of the standard was accompanied by a three-year transition period. This means that a BS OHSAS certificate is no longer valid. Organizations that still wish to transition must undergo a full audit procedure to obtain ISO 45001 certification . Keep in mind that this can require a significant amount of time and resources. However, it is crucial to transition your existing occupational health and safety management system (OHSM system) from BS OHSAS 18001 to ISO 45001 in a well-thought-out and result-oriented manner.
